FIELDThe present invention relates to a user equipment and a base station. Specifically, the user equipment may update a data repetition transmission parameter according to a dynamic indication message transmitted by the base station.
BACKGROUNDWith the rapid development of the wireless communication technology, various applications of wireless communication are ubiquitous in people's life, and demands of the people for wireless communication are also increasing day by day. The 4G mobile communication system (or called the Long Term Evolution (LTE) system) currently available is the main mobile communication system used by most countries.
For some communication applications, e.g., for the application that supports ultra-reliable low latency communication (URLLC) service in the next generation mobile communication system (which is generally called the 5G mobile communication system currently), the user equipment repeatedly transmits the same uplink data (i.e., corresponding to the same transport block from the upper layer) to the base station by using different physical resource blocks, thereby ensuring that the uplink data can be received by the base station. However, in specifications of the current communication system, how the user equipment repeatedly transmits the relevant parameter configuration (e.g., a resource block size, a repetition pattern, a modulation and coding scheme (MCS) and a transmission power or the like) of the uplink data is configured by the base station itself and cannot be dynamically updated according to various conditions of the user equipment. Therefore, the conventional uplink data repetition transmission configuration scheme has drawbacks of a low resource utilization efficiency, fixed spectrum resources, fixed reception delay, being vulnerable to influence of the channel, limited application situation and a low autonomy of the user equipment or the like.
Accordingly, an urgent need exists in the art to provide an uplink data repetition transmission configuration scheme so as to improve the resource utilization efficiency, the using flexibility of the spectrum resources and the flexibility of the reception delay, reduce the influence of the channel, and increase the applications and the autonomy of the user equipment.
SUMMARYThe disclosure includes an uplink data repetition transmission configuration scheme, through which a user equipment may update data repetition transmission parameters according to a dynamic indication message transmitted by the base station. Accordingly, the uplink data repetition transmission configuration scheme may improve the resource utilization efficiency, the using flexibility of the spectrum resources and the flexibility of the reception delay, reduce the influence of the channel, and increase the applications and the autonomy of the user equipment.
The disclosure includes a user equipment which comprises a storage, a transceiver and a processor. The processor is electrically connected to the storage and the transceiver and is configured to execute the following operations: transmitting a first uplink signal to a base station based on a current data repetition transmission parameter; receiving a dynamic indication message from the base station via the transceiver; generating an updated data repetition transmission parameter according to the dynamic indication message after receiving the dynamic indication message; and transmitting a second uplink signal to the base station via the transceiver based on the updated data repetition transmission parameter.
Moreover, the disclosure includes a base station which comprises a storage, a transceiver and a processor. The processor is electrically connected to the storage and the transceiver and is configured to perform the following operations: receiving a first uplink signal from a user equipment via the transceiver, the first uplink signal being transmitted by the user equipment based on a current data repetition transmission parameter; transmitting a dynamic indication message to the user equipment via the transceiver so that the user equipment generates an updated data repetition transmission parameter according to the dynamic indication message and transmits a second uplink signal based on the updated data repetition transmission parameter; and receiving the second uplink signal from the user equipment via the transceiver.
The detailed technology and preferred embodiments implemented for the subject invention are described in the following paragraphs accompanying the appended drawings for people skilled in this field to well appreciate the features of the claimed invention.
In the following description, the present invention will be explained with reference to certain example embodiments thereof. However, these example embodiments are not intended to limit the present invention to any specific examples, embodiments, environment, applications or particular implementations described in these example embodiments. Therefore, description of these example embodiments is only for purpose of illustration rather than to limit the present invention.
It should be appreciated that, in the following embodiments and the attached drawings, elements unrelated to the present invention are omitted from depiction; and dimensional relationships among individual elements in the attached drawings are provided only for ease of understanding, but not to limit the actual scale.
A first embodiment of the present invention is as shown in
As shown in
In the present invention, the user equipment 1 repeatedly transmits the same uplink data (i.e., corresponding to the same transport block from the upper layer) to the base station 2 by using different physical resource blocks, thereby ensuring that the uplink data can be received by the base station 2. In other words, the uplink data repetition transmission configuration scheme of the present invention is applicable to any mobile communication system, having the communication application of repeatedly transmitting the same uplink data by the user equipment.
As shown in
For example, the dynamic indication message 202 may indicate a repetition transmission resource configuration, and the repetition transmission resource configuration comprises at least one of the following data repetition transmission parameters: a resource block size, a repetition pattern, a Modulation and Coding Scheme (MCS) and a transmission power. In other words, the user equipment 1 may adjust the resource block size, the repetition pattern, the MCS and the transmission power for transmitting the subsequent uplink signals in response to the repetition transmission resource configuration.
Moreover, the dynamic indication message 202 may be used in combination with a pre-configured message of Radio Resource Control (RRC) on a physical downlink shared channel (PDSCH). The base station 2 provides multiple sets of pre-configured available data repetition transmission parameters and corresponding time-domain/frequency-domain resource mapping information to the user equipment 1 via the pre-configured message so that the user equipment 1 can subsequently select the corresponding data repetition transmission parameter (i.e., the updated data repetition transmission parameter) in response to the dynamic indication message 202 and transmit the uplink signal on the time-frequency resource corresponding to the updated data repetition transmission parameter based on the time-domain/frequency-domain resource mapping information. The pre-configured message may be a broadcast RRC message or a UE-specific RRC message.
It shall be appreciated by those of ordinary skill in the art that there are connections between the aforesaid data repetition transmission parameters. For example, when the available resource block size becomes greater, the user equipment 1 may use the modulation and coding mode of a lower level for data transmission, e.g., switch from the modulation mode of 64-Quadrature Amplitude Modulation (QAM) to 16-QAM and reduce the coding rate to increase the probability that the base station 2 successfully decoding the uplink signal. Therefore, based on the following description, it shall be readily appreciated by those of ordinary skill in the art that when a transmission parameter of the repetition transmission resource configuration is changed, other relevant transmission parameters may also be changed accordingly, and this will not be further described herein.
Please refer to
In
Thereafter, the user equipment 1 changes the resource block size again after receiving another dynamic indication message 202 at a second time point T2 (before the uplink signal D3-1 is transmitted), and uses the updated resource block size to transmit the uplink signals D3-1 to D3-4 in the next transport block interval (i.e., the third transport block interval TBV3). In this case, the uplink signals D1-3 to D1-4 and the uplink signals D2-1 to D2-4 may be regarded as the first uplink signal 102 which is transmitted based on the data repetition transmission parameter before the second time of updating (i.e., the current data repetition transmission parameter), and the uplink signals D3-1 and D3-4 may be regarded as the second uplink signal 104 which is transmitted based on the data repetition transmission parameter after the second time of updating (i.e., the updated current data repetition transmission parameter).
The first time point T1 and the second time point T2 described above are only used as examples for illustrating the time points at which the user equipment 1 receives the dynamic indication message 202, and are not intended to limit the time points at which the user equipment 1 receives the dynamic indication message 202 in the present invention. Moreover in the present invention, for the time point at which each of the dynamic indication messages is received, the uplink signal transmitted before receiving the dynamic indication message is called the first uplink signal 102 and the data repetition transmission parameter for transmitting the first uplink signal 102 is called the current data repetition transmission parameter, and the uplink signal transmitted after receiving the dynamic indication message is called the second uplink signal 104 and the data repetition transmission parameter for transmitting the second uplink signal 104 is called the updated data repetition transmission parameter.
It shall be appreciated that, in
For example, when the base station 2 successfully decodes the uplink signal D2-1 and the user equipment 1 has received the downlink indication message informing of the successful decoding of the uplink signal D2-1 from the base station 2 before the uplink signal D2-3 is transmitted, the user equipment 1 may terminate the transmission of the uplink signal D2-3 and the uplink signal D2-4 and then directly transmit the uplink signal D3-1. Therefore, under the scheme of early termination of the transport block, the user equipment 1 may stop transmitting the subsequent uplink signal corresponding to the current transport block immediately after the user equipment 1 receives the downlink indication message informing of the successful decoding of the uplink signal from the base station 2. Moreover, in
Please refer to
Similarly, after receiving another dynamic indication message 202 at the second time point T2, the user equipment 1 increases the resource block again for transmitting the uplink signal and reduces the third transport block interval TBV3 according to the repetition transmission resource configuration indicated by the dynamic indication message 202, so the user equipment 1 only transmits the uplink signal D3-1 in the updated third transport block interval TBV3. As described previously, when the available resource block size becomes greater, the user equipment 1 may use the modulation and coding mode of a lower level for data transmission to increase the probability of successfully decoding the uplink signal by the base station 2. Therefore, when the resource block size is increased, the number of times or interval of repetition transmission can be decreased to reduce the reception delay and balance the utilization efficiency of the spectrum resource in the present invention.
It shall be appreciated that, the number of times or interval of repetition transmission is decreased in the implementation scenario of
Please refer to
In detail, referring to
Thereafter, the user equipment 1 updates the resource block size again and keeps transmitting the uplink signals intermittently after receiving another dynamic indication message 202 at the second time point T2 (before the uplink signal D3-1 is transmitted). Therefore, in the third transport block interval TB3, the user equipment 1 uses the updated resource block size to transmit the uplink signals D3-1 and D3-3 discontinuously. It shall be appreciated that, the resource blocks that are suspended for uplink signal transmission (i.e., the resource blocks represented by shaded portions) of
Moreover, in the aforesaid implementation scenarios, the resource blocks for repetition transmission in each of the transport block intervals are continuous resources in term of time. However, as shall be appreciated by those of ordinary skill in the art, the resource blocks for repetition transmission in each of the transport block intervals may also be discontinuous resources in term of time, depending on practical operation requirements of the communication system. For example, a time interval of one or more resource blocks may exist between any two adjacent resource blocks for repetition transmission in each of the transport block intervals.

Moreover, in an embodiment, the resource requirement message 106 may also be implemented by an uplink control message, so the user equipment 1 may transmit the resource requirement message 106 in a Physical Uplink Control Channel (PUCCH). In another embodiment, the resource requirement message 106 may also be implemented by a reference signal, e.g., an Uplink Demodulation Reference Signal (DM-RS) or an Uplink Sounding Reference Signal (SRS). Therefore, specific reference signals may be pre-determined between the base station 2 and the user equipment 1 in advance to serve as the request for resource requirement updating.
A third embodiment of the present invention is as shown in
For example, the repetition transmission parameter updating rule indicates that the user equipment 1 may keep using the current data repetition transmission parameter for subsequent uplink signal transmission when the decoding correctness indicator received by the user equipment 1 indicates ACK. However, when two successive decoding correctness indicators received by the user equipment 1 all indicate NACK, the user equipment 1 may generate an updated data repetition transmission parameter (e.g., update the data repetition transmission parameter downward by a level, and each level may define a specific resource block size, a time-domain repetition pattern, a frequency repetition pattern, an MCS and a transmission power) based on the repetition transmission parameter updating rule and transmit subsequent uplink data according to the updated data repetition transmission parameter. In addition to updating the data repetition transmission parameter downward by a level according to successive NACK, the repetition transmission parameter updating rule may also allow the user equipment 1 to update the data repetition transmission parameter upward by a level according to successive ACK. In this embodiment, updating downward by a level refers to increasing the resource block size, while updating upward by a level refers to decreasing the resource block size.
Still refer to
For example, the repetition transmission resource configuration comprises at least one of the following data repetition transmission parameters: a repetition pattern, a modulation and coding scheme (MCS) and a transmission power. The user equipment 1 generates an updated data repetition transmission parameter according to the decoding correctness indicator, the repetition transmission parameter updating rule and the repetition transmission resource configuration. In other words, in this embodiment, the updating of the resource block size is based on the repetition transmission parameter updating rule (e.g., the resource block size is increased in response to successive NACK and is decreased in response to successive ACK) while other parameters (e.g., the repetition pattern, the MCS and the transmission power) are specifically configured by the base station 2.
Please refer to
A sixth embodiment of the present invention is as shown in
For example, the user equipment 1 may transmit the first uplink signal 102 according to parameters recorded in the data repetition transmission resource configuration sets and corresponding time-domain/frequency-domain resource mapping information depending on transmission requirements of the user equipment 1. If the user equipment 1 determines that all the parameters in the data repetition transmission resource configuration sets that are pre-configured by the base station 2 cannot satisfy the transmission requirements for transmitting the first uplink signal 102, then as described in the second embodiment, the user equipment 1 may transmit the resource requirement message 106 together with the first uplink signal 102 to the base station 2 or transmit the resource requirement message 106 to the base station 2 before the first uplink signal 102 is transmitted so that the base station 2 generates the dynamic indication message 202 in response to the resource requirement message 106, as shown in
It shall be appreciated that, each of the data repetition transmission resource configuration sets may record a combination of different types of parameters. Taking three repetition transmission resource configuration sets as an example for illustration, the first repetition transmission resource configuration set comprises a first resource block size, a first repetition pattern, a first MCS and a first transmission power, the second repetition transmission resource configuration set comprises a second resource block size, a second repetition pattern, a second MCS and a second transmission power, and the third repetition transmission resource configuration set comprises a third resource block size, a third repetition pattern, a third MCS and a third transmission power. Accordingly, the user equipment 1 may select the parameters recorded in one of the data repetition transmission resource configuration sets for transmitting the first uplink signal 102 according to the transmission requirements of the user equipment 1, the channel measurement performed by the user equipment 1 or the user equipment 1 may select randomly (e.g., based on the identification (ID) code of the user equipment). Moreover, the base station 2 may also carry priority selection information in the data repetition transmission resource configuration message 200 so that the user equipment 1 selects the parameters recorded in one of the data repetition transmission resource configuration sets based on the priority selection information.
Moreover, each of the data repetition transmission resource configuration sets may record a combination of the same type of parameters. Taking four repetition transmission resource configuration sets as an example for illustration, the first repetition transmission resource configuration set comprises a first resource block size, a second resource block size, and a third resource block size, the second repetition transmission resource configuration set comprises a first repetition pattern, a second repetition pattern and a third repetition pattern, the third repetition transmission resource configuration set comprises a first MCS, a second MCS and a third MCS, and the fourth repetition transmission resource configuration set comprises a first transmission power, a second transmission power and a third transmission power. Accordingly, the user equipment 1 may select one of the parameters recorded in each of the data repetition transmission resource configuration sets for transmitting the first uplink signal 102 according to the transmission requirements thereof.
